Thank you for the answer, Klaus I have tried your way(commented my subst and added your rows), so now it looks like this:
failure_route[2] { if (!t_is_canceled() && t_check_status("486|408")) { $avp(alias_seq)=$avp(alias_seq)+1; xdbg("HERE WE ARE! $avp(alias_seq)\n"); revert_uri(); sql_query("main", "select username from subscriber where alias='$tU' and alias_seq='$avp(alias_seq)'", "alias_name"); sql_query("main", "select domain from subscriber where alias='$tU' and alias_seq='$avp(alias_seq)'", "alias_domain"); if ($dbr(alias_name=>rows) != 0 && $dbr(alias_domain=>rows) != 0) { subst_uri('/^sip:....@.*$/sip:$dbr(alias_name=>[0,0])@$dbr(alias_domain=>[0,0])/'); # subst('/^To:.*<sip:.*>/To: <sip:$dbr(alias_name=>[0,0])@$dbr(alias_domain=>[0,0])>\r\n/'); <--COMMENTED OUT THIS ONE remove_hf("To"); # <--ADDED THIS ONE append_hf("To: <sip:$dbr(alias_name=>[0,0])@$dbr(alias_domain=>[0,0])>\r\n"); # <--ADDED THIS ONE sql_result_free("alias_name"); sql_result_free("alias_domain"); setflag(10); if (!lookup("location")) { switch ($retcode) { case -1: case -3: t_reply("404", "Not Found"); exit; case -2: exit; } } append_branch(); route(5); } } if (is_method("INVITE")) { unforce_rtp_proxy(); } } route[5] { if (!t_relay()) { sl_reply_error(); } exit; } So the code now supposed to delete "To: <sip:ncm00...@domain.com<sip%3ancm00...@domain.com> >" and to append "To: < sip:ncm00...@domain.com <sip%3ancm00...@domain.com>>" But with ngrep i can see: To: <sip:ncm00...@domain.com <sip%3ancm00...@domain.com>>.Date: Tue, 08 Jun 2010 09:40:10 GMT. With timestamp, which seems to me to be unusual. So maybe it's impossible to rewrite "To" header from failure_route for some reason... (For example according to RFC) Actually my phones ring, and everything works fine, I am just interested with this behavior of Kamailio. Thanks again for your reply. Sincerely yours, Kosilov Fedor. 2010/6/8 Klaus Darilion <klaus.mailingli...@pernau.at> > remove_hf("To"); > append_hf("To: > <sip:$dbr(alias_name=>[0,0])@$dbr(alias_domain=>[0,0])>\r\n"); >
